2. Description of the Related Art As a result of the improvement in living standards, stoves, which are the main indoor heating devices, have also been dismantled from the past oil-based systems, and electric heaters are becoming commonplace. Of course, as social demands increase, various types of electric heaters are being developed.

[0003]

As is well known, a current flows through a heating wire in a certain space protected by a safety net,
The basic operating principle of the electric heater is to heat the surrounding air with the heat generated at this time. At the same time, accessories and other related devices for more efficiently dissipating the heat from the heating wire are provided. As one of the typical examples, an electric heater in which a reflector formed by bending a generally rectangular metal thin plate is provided behind a heating wire has been widely used. However, it has not been so effective. Such a conventional electric heater has a problem in that it cannot be fed to a distance sufficient to satisfy a sufficient amount of heat. In fact, when the amount of current is increased to increase the amount of generated heat itself, there is a danger of overheating and fire.On the other hand, if the amount of current is reduced in consideration of safety, a sufficient amount of heat cannot be obtained. .

In order to solve the problems of such electric heaters, an appropriate amount of heat is sent as far as possible,
A radiant electric heater capable of sufficiently heating indoor air is disclosed in Korean Utility Model Publication No. 98-61527. Such a radiant electric heater is provided with a spherical reflecting plate behind the heating wire, while the heat is not diffused in all directions by having a shape having a diameter that is reduced toward the rear of the heating wire mounting port, so that it is narrow. It is characterized in that it can be sent to a distance in a concentrated area.

Referring to FIGS. 1 and 2, an electric heater 1 is shown.
Are divided into a heating section 10 including a heating wire and a supporting section 20 for supporting the heating section. First, looking at the support portion 20, a main circuit for operating and controlling the radiant electric heater 1 of this example is built in the pedestal 21. further,
A power switch 22 for supplying or cutting off electric power, a temperature control switch 23 for interrupting electric power based on a certain temperature to maintain the temperature of the heating wire in an appropriate state,
A power indicator light 24 indicating OFF, a safety switch 29 for shutting off electric power when the electric heater is tilted, and a safety warning light 25 for calling the user's attention when the electric heater is significantly tilted, etc. It is arranged in the department.

Further, the heat generating part 10 and the pedestal 21 are in the first position.
Are connected via a first support 26 and a second support 27, and by turning the adjustment handle 28, the second support 27 can be inserted into or removed from the first support 26. It has become. That is, the height of the entire heat generating portion 10 can be arbitrarily adjusted. Further, as shown in FIG. 2 in which the heat generating portion of the radiant electric heater of this example is enlarged, the heat generating portion 10 includes a heating wire 12 hidden by a heating wire mounting opening 11 having a predetermined shape and a heating wire 12. A reflector 13 positioned behind the heating wire, and a safety net 1 connected to the reflector 13 to form an outline at the front of the entire heat generating unit 10
4 and a support case 15 connected to the rear end of the reflection plate 13. On the other hand, the heating wire 12 is connected to the reflection plate 13 via a bracket 16, and a heat sensing rod 17 is attached at a predetermined position in front of the reflection plate.

As a result, the heating wire a from the heating wire 12 becomes
Unlike the conventional structure in which the light is diffused in all directions, the light is concentrated in the predetermined range C by the reflection plate 13, and as a result, it can reach a considerably long distance that requires hot air. At this time, the heating wire a does not stay around the heating part 10 including the heating wire 12 but is immediately diverged through the reflection process by the reflector 13, so that the safety net 1
4 is also prevented.

Here, when the reflector 13 has a parabolic shape with a concave center, including a spherical surface such as an ordinary concave mirror, the maximum heat ray concentration phenomenon can be obtained. On the other hand, the heating wire mounting port 11 around which the heating wire 12 is wound and which is usually made of a heat-resistant material such as ceramics has a truncated cone or conical shape having a diameter that decreases toward the rear. This means that the heating wire a from the heating wire 12
By turning to the direction of 3, a part of the heat ray is fixed to a certain range C.
This is to prevent dispersion outside.

The purpose of this example can be sufficiently achieved even if the shape of the mounting opening 11 is not a truncated cone, for example, a triangular pyramid or another polygonal pyramid. In other words, any one can be used as long as the attachment opening 11 has a diameter that reduces toward the rear. However, although it is true that such an electric heater has good thermal efficiency, since the heating wire of the electric heater that generates heat is a coil,
If used for a long time, there is a problem that the coil is corroded, the use durability is reduced, and there is a risk of fire.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to use a halogen lamp as a heater and place an auxiliary reflector in front of the halogen lamp to increase the reflection efficiency. Another object of the present invention is to provide a heater that increases durability.

In the present invention, the halogen lamp fixing plate 50 and the reflecting plate 30 are connected and fixed by screws via the screw holes 52. Further, the halogen lamp 40 is connected to the halogen lamp fixing plate 50 and connected to a power supply line (not shown). Further, a reflector fixing hole 32 is fixedly installed at a central portion of a safety net 31 used in combination with the reflector 30 so as to face the reflector 30. An auxiliary reflector 60 is fixedly installed in the reflector fixing opening 32 so that the concave surface faces the reflector 30. Of course, the auxiliary reflection plate 60 is provided so as not to touch the central portion of the halogen lamp 40.

The electric heater according to the present invention includes an adjusting knob 35.
When a power switch is turned on using a voltage, a voltage is applied to the halogen lamp 40 and the halogen lamp 40 generates heat. The generated heat ray (for example, H1) is applied to the reflector 30 by 1
Next, it is reflected and reaches the user, or another heat ray (for example, H
2) is primarily reflected by the auxiliary reflector 60, and then reflected by the reflector 3
At 0, it is secondarily reflected and reaches the user. In other words, in the conventional case, only the heat component due to the primary reflection is radiated as shown in FIG.
Since the light is radiated including the secondary reflection component, the amount of heat radiated sharply increases, and the heat generation effect becomes relatively high.

Further, since the auxiliary reflecting plate 60 is provided on the entire surface of the halogen lamp 40, it is possible to prevent a child from directly touching the lamp with a sharp object (for example, chopsticks), thereby providing an effect of protecting the lamp. Further, since the height of the halogen lamp fixing plate 50 is low and it is almost integrally fixed to the reflecting plate 30, installation is easy. Further, since the fixing plate 50 does not hinder the heat transfer, the heat efficiency is improved accordingly.
